  • Patent number: 6465565
    Abstract: Anionic waterborne polyurethane dispersions are formed in the presence of polyfluorooxetane oligomers, polymers, or copolymers so that the polyfluorooxetanes are incorporated in the polyurethane. Coatings made from such polyurethanes have good low temperature flexibility, good chemical resistance and abrasion resistance, as well as a low coefficient of friction. Alternatively, the anionic water borne polyurethane dispersion can be blended with vinyl ester monomers such as various acrylates and subsequently polymerized by radiation, for example ultraviolet light, to form a comingled blend of at least two different types of polymers.
    Type: Grant

Another embodiment relates to a preformed copolymer made by reacting the polyfluorooxetane oligomer, polymer, or copolymer with a polycarboxylic acid such as a dicarboxylic acid and subsequently reacting the same with a polyol intermediate, such as a polymer, or with monomers forming the polyol intermediate.

  • Publication number: 20020143112
    Abstract: Monofunctional polyfluorooxetane oligomers and polymers are prepared by the cationic polymerization of fluorooxetane monomers with a monoalcohol. The fluorooxetane oligomers or polymers can be copolymerized with generally cyclic ethers. Alternatively, the polyfluorooxetane oligomer or polymer having a single hydroxyl end group can be functionalized with a variety of compounds so as to yield a functional end group such as an acrylate, a methacrylate, an allylic, an amine, etc., with the functionalized oligomer or polymer being suitable for use in radiation curable or thermal curable coating compositions. These functionalized polymers can be copolymerized and cured to provide improvements in wetting and surface properties that have previously been provided by migratory chemicals such as waxes and oils.

  • Publication number: 20020127420
    Abstract: A polyoxetane-polyester polymer comprising a hydroxyl terminated polyoxetane prepolymer containing repeat units derived from polymerized oxetane monomers having one or two pendant —CH2—O—(CH2)n—Rf groups wherein Rf is partially or fully fluorinated, where the polyoxetane prepolymer is esterified with polyester forming reactants to form the polyoxetane-polyester polymer, and said polymer is mixed with a reactive lower alkyl etherified melamine-formaldehyde to form a thermoformable coating composition. The coating composition is partially cured in a first stage heating at less than about 180° F. to provide a thermoformable partially cured, tack-free, non-blocking, coating layer, followed by application to generally a contoured substrate and thermoformed to conform thereto. The contoured partially cured coating layer is then heat cured at temperatures above at least 180° F. for time sufficient to form a cured coating.

  • Patent number: 6436540
    Abstract: A co-mingled polyurethane-polyvinyl ester composition can be used as a coating, which has good scratch, mar and solvent resistance. The coating is derived from a waterborne polyurethane solution containing free radically polymerizable monomers such as acrylate, ultraviolet light initiators, and optionally urethane crosslinking agents. A process for forming the co-mingled polyurethane-polyvinyl ester composition comprises drying the waterborne polyurethane containing the polymerizable monomers therein and radiation polymerizing, as by ultraviolet light, the free radically polymerizable monomers on a substrate such as a plastic sheet to form a laminate. Subsequently, the laminate can be utilized to form a coating on a product as by thermoforming, where if urethane crosslinking agents are utilized, the polyurethane will be crosslinked.
